Re: fopen() of a read-only file for writing?

Ok,

I changed the mount parameters in fstab from 'defaults' (hey, it was 2003)
to:

    mount -t vfat -o user,exec,suid,rw,uid=1054,gid=269,shortname=mixed
/dev/hda8   /data

That worked wonders, the user and uid parts being key. I haven't checked
whether suid was necessary. Now, I can work directly on the data again, as a
normal user.

-----
I found CAP_DAC_OVERRIDE -- definitely don't want to go there.
